I found this cheat sheet for ipv6. It is very handy as it includes a column for ipv4 equivalents.
http://www.ripe.net/lir-services/new-lir/ipv6_reference_card.pdf
Through this I was able to confirm that:
FF00:: is for multicast addresses and is similar to 224.0.0.0
2001:: is for Teredo (allows ipv6 to tunnel through ipv4 NATs)
FC00: and FD00: are called Unique Local Addresses or ULAS and are similar to private IPs in IP4 (ala 192.168/172.16/10.0.0)
FE80: are Link Local Addresses and are similar to the APIPA address (169.254)
